DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an identification number communication device for transmitting an identification number of a built-in device to an external reading device.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram showing a configuration of a conventional identification number communication device. Identification number communication device 11 in FIG.
Is a processor 12, a memory 13, and a communication unit 1.
4 is connected via an internal bus 15. The identification number communication device 11 is incorporated in a device that needs to be identified by an identification number (hereinafter referred to as an “ID number”).

[0005] A memory 13 is for storing an ID number, and is constituted by a nonvolatile memory.

The communication unit 14 is for communicating with an external reading device 17 and reads the ID number of the device in which the identification number communication device 11 is incorporated.
Send to

The processor 12 controls writing and reading of ID numbers to and from the memory 13 and controls the communication unit 14.

[0006] The identification number communication device 11 is a reading device 1.
7 when an inquiry is received from the memory 13
, And returns this ID number to the reading device 17 via the communication unit 14.

As a result, the ID number is obtained by the reading device 17.

[0008]

In such a conventional identification number communication device 11, since an ID number can be written into the memory 13 by the processor 12, a malicious third party falsifies the ID number. It is possible to read an invalid ID number and return it to the device 17.

[0009] The present invention has been made in view of the above, and an object of the present invention is to provide an identification number communication device capable of preventing falsification of an ID number.

[0010]

In order to achieve the above object, according to the present invention, there is provided an identification number communication apparatus which is incorporated in a device and used to store the identification number of the device in a non-rewritable manner. Storage means, and a transmission means for transmitting the identification number to an external reading device.

In the present invention, the identification number is stored in a non-rewritable manner to prevent the ID number from being falsified.

According to a second aspect of the present invention, in the identification number communication apparatus according to the first aspect, the transmitting means directly accesses the storage means to read out the identification number.

According to the present invention, the transmission means directly accesses the storage means storing the identification number and reads the identification number, thereby preventing the falsified ID number from being sent to the transmission means. Like that.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of an identification number communication device according to one embodiment. The identification number communication device 1 in FIG. 1 has a configuration in which a processor 2, a memory 3, a communication unit 4, and an ID chip 6 are connected via an internal bus 5. The identification number communication device 1 is incorporated in a device that needs to be identified by an ID number.

The ID chip 6 is for storing the ID number of the device in a non-rewritable manner by a hardware configuration, and is composed of, for example, a ROM (Read Only Memory) or the like.

The memory 3 is for storing necessary information other than the ID number, and is constituted by a nonvolatile memory or the like.

The processor 2 controls writing and reading of information to and from the memory 3, controls reading of an ID number from the ID chip 6, and controls the communication unit 4.

The communication unit 4 includes an external reading device 7
It is for communicating with a contact or non-contact interface. When there is an inquiry from the reading device 7, the ID number is read directly by accessing the ID chip 6 without depending on the reading control to the ID chip 6 by the processor 12 and transmitted to the reading device 7.

The identification number communication device 1 thus configured
As a specific example of a device in which is incorporated, a credit IC card and its reading device itself can be considered, for example.

When the identification number communication device 1 is incorporated in a credit IC card, the identification number communication device 1 is arranged on one credit IC card. And the ID
The chip 6 has an I for identifying the credit IC card.
The D number is stored, and the member number and the like are stored in the memory 3.

When there is an inquiry from the reading device 7, the communication unit 4 reads the ID number from the ID chip 6, the processor 2 reads the member information and the like from the memory 3, and the communication unit 4 The information is read and transmitted to the device 7.

At this time, data such as an ID number and member information is transmitted from the reading device 7 to a terminal in the credit bureau through a network (not shown). In this terminal, the authenticity of the credit IC card is determined by comparing the previously registered ID number and member information with the transmitted ID number and member information. This prevents unauthorized use by copying or the like.

If the identification number communication device 1 is incorporated in a credit IC card reader, the ID number of the reader cannot be falsified, so that the credit inspection organization periodically checks the ID number. This makes it possible to monitor replacement or theft of the reading device.

Therefore, according to the present embodiment, since the ID number of the device is stored in the ID chip 6 by the hardware configuration, the ID number cannot be rewritten. Can be prevented.

Further, according to the present embodiment, when there is an inquiry from the reading device 7, the communication unit 4
However, by directly accessing the ID chip 6 and reading out the ID number, the I
The transmission of the D number to the communication unit 4 can be prevented.

[0027]

As described above, according to the identification number communication apparatus according to the first aspect of the present invention, the identification number is stored in a non-rewritable manner, thereby preventing the ID number from being falsified. Can be.

According to the identification number communication apparatus according to the present invention, the transmission means directly accesses the storage means to read out the identification number, so that the altered I number is read.
It is possible to prevent the D number from being sent to the transmitting means.
